Francine, You have left us a little in the dark. Some more info would be a good idea if you need to see detailed responses. I recently had the opportunity to move about 60 containers with about 200 or so fish, so I feel comfortable about making some observations. Granted the fish were mostly Rivulus, but the concepts would be the same. The water between the two locations was radically different. I lowered the water in the tanks to about 1 1/2 inches, leaving all plants, gravel and filter in the water. I slid the tanks into the back of my van (carpeted) and drove the nearly 2 hours back to my place. When I got here, I added about 1 1/2 inches of my water (softer and neutral vs hard and alkaline)...the weather cooperated. Some of the tanks were not completely changed over for nearly 2 weeks. I did water changes on those tanks at about a week. These tanks had been neglected for a couple of months because of a severe illness of the owner and were extremely overgrown. I'm of the opinion that the overgrown situation may have played in my favor with respect to the bacteria. I did remove a number of the plants which seemed to be on the edge of health. I did not want them to start to decay. I did not add air into some of the tanks for the two weeks...just ran out of energy and time. Some of the tanks were stacked on the floor for a couple of days. It does not appear that we lost any fish in the process. Part of that would because they were fed sparingly (cutting down on the metabolism) and kept in the dark (for the most part) when they arrived (also cutting down on the metabolism)...the weather was not too hot which helped with O2 in the water and the metabolism also. I had to make two trips on two days...I have one more to go (another 20 units or so). Francine...test the water in both locations. Remember to run the tap for a few minutes to get a better reading...test fresh and after sitting an hour...test the next morning again. If you can set a 55 gallon drum with water at the new location prior to the move you will be better off. I had the advantage of having water readily available. If there is an opportunity to construct the racks ahead of time, by all means. Racks are fairly inexpensive to build...time not factored as a cost. If I had to move my entire fish room, I would walk away from the built in racks and construct new ones on the other end...and I love the ones I have and would build more just like them. Oh...I clean the filters(sponge) or rather rinsed them as I set the tanks back up. I was relying on the bacteria from the tank walls, gravel and that which was left in the filter as being enough to get me back to speed. I change water every week, so ammonia was not a challenge with the bio-load that I was faced with (rather low). O2 could be your biggest enemy. The level of O2 drops something like half for every 10 degree rise in temperature...lower water can get warmer faster...and then again lower water can keep the surface area to gallon ratio better...it's a fine line to walk. The bacteria needs the O2 also. The fry made the move fine. If you think that breaking the tanks down was hard...let me warn you...by the time you drag yourself our of the vehicle and look in the back and realize that you have to reverse the process AND clean the units as you go...you will be exhausted. Double your allotted time on the move. Test the water ahead of time. Set water up prior to the move. Lower the water in the tanks. Leave the gravel in. Leave the filters in. Don't feed too much. Keep the fish in the dark (they will not be as frightened either)...watch the temperature...hot is bad, cooler is better.
